Here is a guide to some commonly used terms in the chainsaw world!

Bar: Also known as a guide bar, this is the metal bar that protrudes from the front of the saw, this is what the chain runs around and is used to guide the chain and make the cut.

Bucking: The act of cutting a tree that has been cut down into smaller, easier to manage logs.

Chain: The part of the chainsaw that actually does the cutting, it is very sharp and comes in multiple varieties.

Chain Brake: Quickly cuts off the power to the chainsaw in case of kick back or an accident

Chain Catcher: In case of the chain breaking or becoming derailed, this will keep the chain from being thrown back toward the operator.

Chain Gauge: The gauge of a chain is the width of the drive link that will fit into the guide bar.

Chain Pitch: There are 4 variants of chain pitch. The chain pitch is determined by measuring the distance (in inches) between 3 rivets that are consecutive, and dividing the measurement by two.

Chain Tensioner: Tool used to adjust the tension-or tightness- of the chain on the saw.

Chisel Chains: Designed with a pointed square corner for maximum chisel performance and speed.
